Filed: 1983-07-15
Abstract: PURPOSE:To improve remarkably the temperature characteristic of an oscillation frequency by making an injection current have a temperature variation of a base voltage of an inversion element. CONSTITUTION:The same injection current iINJ as an inversion element 3 flows to a reference voltage source 1 by a current source 12. Also, the current of a current source 13 becomes a current quantity of two times of the whole injection current IINJ. Accordingly, transistors (TR)14-17 and 5 become the same current. Therefore, the base-emitter voltages VBE of NPN TRs 14, 15 are the same, and to VBE of PNP TRs 16-18 and 5 is also the same. In this way, a voltage VR impressed across both ends of a variable resistor 4 for determining the injection current IINJ of a digital oscillator 1 is made equal to a voltage produced by the stacked inversion elements to improve remarkably to temperature characteristic of the oscillation frequency.
